Features:
Multiple Protection Options: Thermomagnetic type provides basic overload + short circuit protection; single-magnetic type adapts to the full current range protection of motors; electronic type (250A and above) supports four-stage protection: overload, short circuit, instantaneous trip, and ground fault, adapting to complex power distribution needs.
Breakdown and Safety: Breaking capacity 8-55kA, adaptable to different short circuit levels in various scenarios; phase separators and terminal covers enhance insulation safety and reduce arc risk.
Installation and Maintenance: Insert-type base supports front/rear panel installation for easy replacement and maintenance; door coupling handle allows for external cabinet operation, improving maintenance convenience.
Flexible Accessories: Modular internal and external accessories allow for the addition of shunt excitation, undervoltage, auxiliary contacts, etc., adaptable to various control circuits.
Intelligent and Convenient: Each product comes with a QR code; scanning the code quickly obtains technical data, wiring diagrams, and tripping curves, simplifying selection and maintenance.
Typical Applications:
Industrial Sector: Factory secondary power distribution, motor control circuits (single magnetic trip adapter), frequency converter control cabinets, energy storage systems, suitable for high short-circuit levels and frequent start-stop scenarios.
Public and Commercial Buildings and Infrastructure: Building power distribution trunk lines, power circuits for air conditioning/water pumps, data center UPS input terminals; plug-in installation facilitates maintenance.
Residential and Small Commercial Buildings: Main switches and branch circuit protection in distribution boxes; thermal-magnetic type provides basic reliable protection.
